How to use environment values inside the template

[rkmax]

Example I have the following in my index.html

<!-- build:template    
    <% if (environment === 'production') { %>
    <script>
      (function(i,s,o,g,r,a,m){i['GoogleAnalyticsObject']=r;i[r]=i[r]||function(){
        (i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o),
      m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m)
      })(window,document,'script','//www.google-analytics.com/analytics.js','ga');

      ga('create', '<%= GOOGLE_TRACKING_ID %>', 'auto');
      ga('send', 'pageview');
    </script>
    <% } %>
    /build -->

you have to pass the data of the template from your Gruntfile.

here is a quick draft

Gruntfile.js

module.exports = function (grunt) {
  grunt.initConfig({
    processhtml: {
      template: {
        options: {
          data: {
            googleTrackingId: process.env.GOOGLE_TRACKING_ID
          }
        },
        files: [{
          'dist/template.html': ['template.html']
        }]
      },
    }
  });

  grunt.registerTask('default', ['processhtml']);
};

template.html

<!-- build:template    
    <% if (environment === 'production') { %>
    <script>
      (function(i,s,o,g,r,a,m){i['GoogleAnalyticsObject']=r;i[r]=i[r]||function(){
        (i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o),
      m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m)
      })(window,document,'script','//www.google-analytics.com/analytics.js','ga');

      ga('create', '<%= googleTrackingId %>', 'auto');
      ga('send', 'pageview');
    </script>
    <% } %>
    /build -->
